ANGLE-HANGER FOR MECHANECAL=TELEPHONE LINES.

SPECIFICATION forming part of Letters Patent No. 390.062, datedSeptember 25, 1888.

Application filed November 15- 1887.

To all whom it may concern:

Be it known that I, ROBERT C. M. BOWLES, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented a new and useful Improvement in Telephone-Lines, of whichthe following is a specification.

In the various devices for dealing with an gles in a telephone-line theprevailing idea is to subdivide said anglesparticularly if a right angleor nearly sointo two or more obtuse angles, and to suspend the line atthe respective apices of said subdividing angles. Assuming said idea ofsubdivision to be correct and that the more subdivisions the better, thelogical result is infinitesimal subdivisiona curve. I have thereforeconceived the idea of introducing intothe line at the points thereof asoccur such angles as mentioned, as an immediate attachment, part, andcontinuation thereof, a curved tempered elastic metal bar, preferablycurved before tempering to nearly the required angle, the tension of theline completing its adjustment. The line is subtended at or near themiddle of said bar by a single guy, not bound or fixed, but passingloosely through the loop of said guy, thus rendering it automatic andselfadjusting. Every point of attachment of the line between thetelephones being a source oi vibrations and consequent injury, thissingle guy, instead of two or more, as used in other devices, is initself an improvement.

Another important point claimed for this invention is that by its usethe angle can be located at the very point of the liues issuance fromthe telephone, thus making it practicable to carry the lineperpendicularly from said issuing-pointa very desirable thing to do in amajority of cases.

I am aware that various devices have been introduced into the straightportions of the line for certain purposes such as a bar with loopedends, or the doublelink of a chain, or of other straight for1n-but allof these are used for purposes entirely different from that of thisinvention, nor do they effect its pur- Serial X0. 9.55.259.

poses. Again, a contrivauce of the form and nature of a turning-fork hasbeen devised, capable, if required, of changing the direction of theline; but this device is fixed to its sup port and makes angularconnection with the line, which is the very objection that this invention is intended to and does remove.

In the drawings, forming part of this specification, Figurel is a viewof the bar for making the 1ine-connection. Fig. 2 is a view showing thebar in line-connection and subtended by guy.

In the drawings, A represents the bar for making the line-connection.This baris made curving from end to end and of spring-tempered elasticmetal, preferably curved to near a quadrant. Each end B O of the bar ismade of hook or loop shape for convenience in connecting with thesections D D of the line. E is the loop of guy, which guy is attached toits support at F. The bar A passes loosely through said loop of guy, andthis freedom, coupled with its elasticity, renders it capable ofadaptation to any required angle.

Thus constituted, constructed, and adjusted the bar forms a very neatand simple con nected curvilinear continuation of the sections of theline and overcomes to alarge extent the great obstacle to satisfactoryresults in the operating of telephone-linesnamely, angles.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

In combination with a telephone-line, a curving bar,A, made of elastictempered metal adapted at each end for connection with theline-sections, and the loop E of a subtending guy, through which loopsaid bar loosely passes, substantially as described, and for the purposespecified.

In testimony of which I tifilX my signature in presence of twowitnesses.

ROBERT C. M. BOWLES.

Correction in Letters Patent No. 390,062.

It is hereby certified that in Letters Patent No. 390,062, grantedSeptember 25, 1888, upon the application of Robert G. M. Bowles, ofBoston, Massachusetts, for an improvement in Angle-Hangers forMechanical-Telephone Lines, an error appears in the printedspecification requiring the following correction: In line 4:9 thecompound word turning-fork should be stricken out and the compound Wordtaming fork inserted instead; and that the said Letters Patent should beread with this correction therein that the same may conform to therecord of the case in the Patent Ofiice.
